What stock bike might that be and with what cam? Still not buying it. Sorry but these bikes just don't crack 120 because you change the cam and exhaust. Just not enough HP. Now if you're including headwork, then it becomes doable.

Either you struggled in high school math or you REALLY enjoy looking at LED tailights

My wifew Dyna LowRider will do it, easily. Not all cams fall of at 4000 RPM's. I bury her speedo every single time I ride her bike. 96", V&H straight shots, SE 211 cams, SE stage I a/c, SERT tuned by me. Here's her sheet. And when I had the 211's in my bike with the stock bore, heads, I could hit 120 as well. I've been 146 on it now with it's current set up and had a little throttle left. My brothers '05 road king with airbox and hooker slip ons has been to 112 with a GPS. Speedo read higher, but the GPS hit 112.

Where's the dyno of the bike that's running 146? My guess is that you'll need close to or over 120hp to hit 146mph on a Dyna. Maybe even 130hp.
The 112 on a stock RK sounds about right.
That dyno and the 95 hp peak at 6k, I would say it's possible on a lightweight Dyna to hit 120 but I still doubt it's able to hit 120 unless you're getting that speed off a GPS. My guess is at 120 on the bike's speedo you're probably 4-5mph "happy".

I didn't have a GPS on my wifes, just going off the speedo, but it was burried. I suppose I can put a GPS on it but I don't see the point as I have no dog in this fight and nothing to prove. As far as my bike goes, yes I am over 120 HP, and yes you are correct, the speedo is happy by around 4 MPH, I hit 146 with a Garmin GPS mounted on my handlebars, so i wasn't going by the speedo. The nice thing about the GPS is that it hold the top speed for you, so it was after I parked it that I saw I hit 146, had I been watching it while I was riding I would've pushed it to 150 since I had more left in it. I don't have a current dyno sheet on this computer of my bike, but I have one of what it was before I changed the cams again. It was 129 HP and 121 TRQ, but, like I said, that was the previous build.

Now that definitely makes sense. With 129hp on a light bike like a dyna, you should be capable of the speeds you're talking about. Now whether the Dyna's frame, wheels, tires and wheel bearings are able to handle those speeds is an entirely different question but that kind of hp should definitely push a light sled like a dyno to those speeds.
Now for the other poster that thinks he's hitting 120mph on his speedo with maybe 70 hp on a heavier sled like a softail classic with a shield and bags...well .....that does sound like a dream and one of those dreams that has a "happy ending"
